JACOB L. COLE AND DENZEL R. GUM?, OF BRAVE, PENNSYLVANIA.

Application filed Novembe Our invention whereby tie rods, machine elements may and its ADJUSTABLE BOLT.

relates to adjustable bolts spring hangers or other be connected together', principal. object is to provide a bolt which can be readily adjusted to take up wear between the connected parts.

A further object of provide a wear compensating bolt be readily and quickly the invention is to which can adjusted and used in connection with various kinds of machine elements.

lith the preceding advantages in mind, in the novel combination of elements, constructions of parts and oper specilically referred to, claimed trated in the accompanying' wherein:

Figure l is a view partly in section of and other o and arr bjects and the invention consist-s and arrangement a ngenients ations to he hereinafter and illusdrawings,

partly in elevation and an adjustable bolt construrted in accordance with my invention.

Figure of the same.

Figure 3 is a detail. view of t 9. is a fragmentary side elevation he several units embodied in the invention, and

Figure 4 is an angles to Figure 3.

Referring to the drawings wherein corresponding end elevation taken at right in detail,

characters of reference denote corresponding parts throughout the several views, the numeral 5 a` machine part provided with a bushing t while 7 arms operatively associated with ing orsleeve G.

The above parts form no ent invention but are merel f the application of the invention.

designates sleeve or shows a pair of parallel the bushpart of the presillustrative of Our invention comprises a four sided tapered bolt l0 j which threaded ends received. Nuts 12 are threaded ends l1 and are retained in locke by means of lock washers 13,

passes longitudinally through the sleeve t and has reduced 11 upon which the parts 7 'are upon the d position v tures.

r 12, 1924. Serial No. 749,508.

Embracing the bolt l() is a pair of tapered semi-cylindrical shim sections 14 whose inner faces are provided with V- shaped in cross section recesses l5 to enibrace the fiat sides of the bolt 10.

As shown these shims are tapered to the taper of the bolt l0 and as the bore of the sleeve 6 wears these shims are adjusted l0ngitueinally by means of adjusting screws 16 threaded through one of the members 7 and have their ends engaged in recesses 17 in the end of these shims.

From the disclosure it will be apparent that we have provided a simple and inexpensive adjustable bolt which can be readily used in connecting various kinds of machine elements and when wear between the parts occurs, it can be compensated `for by adjusting the shims as above stated.

Thilo we have shown and described the preferred embodiment of the invention,we desire to have it understood that we do not limit ourselves to what is herein shown and described, as such changes may be made in theform, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.

Vhat is claimed iss* A device of the character described comprising a machine part having a sleeve, afour sided bolt passing through the sleeve', threaded lextensions formed on the four sided bolt, nuts arranged on the threaded eX tensions and holding machine elements in place, a plurality of shims embracing the four sided bolt and formed with recesses to conform with the sides of the bolt, the shims being` tapered longitudinally and adjusting screws on one of the machine elements and engaging the adjacent ends of the shims whereby to adjust the saine-longitudinally.v

In testimony whereof we affix our signaq JAooB L. ooLE. pENznL a. eUMP.
